Please read details. What is the best thing to do on a first date with a friend you already know well? Is dinner okay?

I have a friend I've became close with in the past 6 months of college. There's always been some unresolved sexual tension and I finally asked her out a couple weeks ago. It's hard to picture a first date, because we've already covered a lot of the first-date type conversations and been alone plenty of times, but we are going today. I just don't want it to feel like we are "friends hanging out."
